ADJUSTABLE ELECTROLIER.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed March 13, 1905. Serial No. 249,904.

To all whom it may concern:

Be it known that I, HENRY C. AYREs, a citizen of the United States, residing at Greenville, in the county of Darke and State of Ohio, have invented certain new and useful 1mprovements in Adjustable Electroliers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in devices for coiling and uncoiling electrical conductors, and especially in the application of a device of this nature in combination with electroliers, telephones, &c., and comprises, essentially, a spring-actuated winding-drum about which conductor-wires are adapted to be wound and so arranged that the wires will be fed out or wound up accordingly as the telescoping sections of the electrolier are extended or retracted.

The invention consists, further, in various details of construction and in combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended clai'm.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a sectional View longitudinally through the telescoping portions of an electrolier, parts being shown in elevation. Fig. 2 is a side elevation of the invention. Fig. 3 is a sectional view through the winding-d rum, and Fig. 4 is a cross-sectional view upon line 4 L of Fig. 1.

Reference now being had to the details of the drawings by letter, A designates a yoke which has its upper ends connected by means of a cross-piece B, which cross-piece is provided with apertures B, through which the conductor-wires C are adapted to pass. A shaft D is mounted in the arms of said yoke, and a grooved drum or pulley E is fixed to said shaft. The base portion of said yoke has a central aperture the walls of which are threaded and adapted to receive a tubular portion F, which has a flaring ornamental part F near its lower end from which bracketarms may extend if it is desired to mount a plurality of lights upon the casing. Mounted to have a telescoping movement within the tubular part F is a tubing Gr, having a flange G at its upper end designed to snugly fit against the inner surface of the tubing F. An incandescent lamp H is fitted within the lower end of the tubing G and has connected thereto the conductor-wires C, which pass through the two tubings F and G and wind about the drum E in the manner shown. Said wires C are coiled about the shaft D, as shown clearly in Fig. 1 of the drawings, to allow for the lowering of the lamp, it being understood that as the drum winds in one direction the coil of wire will unwind from the shaft D to allow the two tubes to be extended and with the inner tube the incandescent bulb. Said conductorwires pass through the apertures in the flange on the drum and winding about the shaft pass to the source of supply of the electrical current. In order'to cause the conductor-wires to wind upon the drum, 1 provide a spring N, one end of which is fastened to the shaft D and the other end to the drum, whereby as the tubular portions are extended the spring will be under tension and cause the conductor-wires to wind up as the telescoping sections close together. In order to equalize the tension of the spring and hold the lamp at any adjusted position, I provide a friction device which may be of any suitable construction adapted for the purpose, and said attachment which 1 have shown comprises two blocks 0 and O', which are connected together, and Q, designates a bail fastened at Q to the block O and carries an adjusting-screw 'R, the end of which is adapted to bear against a spring J for the purpose of causing the blocks to frictionally engage the circumference of the tubing G.

From the foregoing it will be observed that by the provision of my improved apparatus means is provided for holding an incandescent light in different positions, the conductorwires winding and unwinding accordingly as the parts are closed together or extended.

While I have shown my device as applied to an electrolier, it will be understood that it may be applied for various uses in telephoning or other purposes in which it is desired to carry conductor-wires, and it will be understood that I do not confine my invention to the particular construction shown, but may vary the details of the same, if desired, without in any way departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent. is

In combination with a yoke, provided with arms, and having a cross-piece connecting the upper ends thereof, said cross-piece having apertures in its projecting ends, a stationary shaft mounted in said yoke, a spring-actuated" having connection therewith, a tubing telescoping within said casing, friction-blocks O and O, which are connected together and mounted upon the casing, a bail fixed to one of said blocks, an adjusting-screw carried by said bail, a spring mounted upon the other of said blocks and adapted to be engaged by said screw, whereby the blocks may be held frictionally against said tubing, and an electric light carried by the latter, as set forth.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.

HENRY O. AYRES.
